IMPROVEMENT IN TELL-ALARMS.

Specific-ation formirg part of Leiters Patent No. l15,777, dated D.emit-163, 1873; application filed November 1, 1873.

To all whom it may concern:

Be it known that I, J onN F. BALDwiN, of Nashua, in the county ofHillsborough and State of New Hampshire, have invented a new and usefulImprovement in Alarm -Tills, of which the following is a specification:

Figure l-is a longitudinal section of a till to which my improved devicehas been applied, taken through the line x a, Fig'. 2. Fig. 2 is a topview of the inner part of the same withdrawn. Fig. 3 is an under-sideview of a part of the cover of the same. Fig. 4 is acrosssection of thesame, taken through the line y y, Fig. 2. Fig. 5 is a detail view of theratchet.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described, and then pointed out in theclaim.

A represents the till or drawer7 which moves out and in upon cleatsattached to the cover B, which may be a counter, table, desk, or otherstationary board. The receptacle in which the bolts and levers areplaced and work consists of the box C, the front and sides of which arecast in one piece, and the rear side of which is closed by theguide-plate D. The plate D and front side of the box C are made withshoulders or offsets in their middle parts, to form in the upper part anarrow space to receive the bolts, and in the lower part a wider spaceto receive the levers, which levers and bolts are kept in placelaterally by points east upon the inner sides of said plates. Theguideplate D has cross-flan ges formed across its rear side to restagainst the end of the till or drawer, and hold the said guide-plateDerect while it is held in place by th'e box O. The box C is secured .inplace by screws passing 4 through lugs cast upon the lower edge of itsfront and the top of its sides, as shown in Figs.

2 and Ll. E are the bolts, the bodies of which fit into the upperchamber of the box C D, and the top of which projects in front and reart0 rest upon the upper edges of the box C and guide-plate D. The lowerends of the bolts E are inclined, as shown in Fig. l, and rest upon theupper ends of the one-armed levers F. The levers F 4are made in theshape shown in Fig. l. In the rear edge of the levers F is formed anotch to receive the edge of the cross-iian ge G, formed upon theguidefplate D, to support the said levers and serve as their fulerum.Upon the lower part of the single-'armed levers F is cast a point toreceive one end of a coiled spring, H, the other end of which isreceived upon a point forlned upon the inner surface of the front of thebox C. By this construction, when the lower parts of the oncarmed leversF are held back by the springs H, their upper ends are inclined tocorrespond with the inclined lower ends of the bolts E. Vhen the bolts Eare so arranged that the inclination of their lower ends may correspondwith the inclination of the tops of the levers F, the forward movementof the lower ends of said levers F will raise the said bolts 5 but whenthe bolts E are reversed, as shown in dotted lines in Fig. 1, theforward movement of the lower ends of the said levers F will lower thebolts E. I is a plate, which is secured to the cover B in such aposition as to be directly over the parts of the alarm attached to thetill or drawer A when said drawer or till is closed. To the forward partof the plate I is pivoted the forward edge of the plate J, the rear orfree part of which is held down by a spring, K, placed between it andthe cover B. rllhe rear edge of the plate I, when the drawer is closed,rests upon the tops of the bolts E and against the lugs or inclines L,cast upon the upwardly-projecting sides ofthe box A. Upon the side edgesofthe rear part of the plate J are formed lugs M, of a length equal tothe length of the inclined lugs L. By

this construction, when all the bolts E are down, the lugs M, when thedrawer or till is drawn outward, will pass out beneath the lugs L; butshould the till or drawer be drawn upon without all the bolts beingdown, the lugs M will strike against and cannot pass the lugs L. "Whent-he drawer is pushed shut, the lugs M -slide up the inclined sides ofthe lugs L, and

drop down in front of them. Nis abent ratchet or lever-catch, which ispivoted at its angle to the upper part of the side of the boX A, in sucha position that the lug n', formed upon the upper end of said ratchet,may project along the forward side of one of the lugs L. rEhe lug n ofthe ratchet N is held out from the lug L, and the other or engaging endof said ratchet is held raised, so that its hook or catch end may catchupon the lever O, to the end of which is attached the bell-hammer P forstriking` the gong Q. The other end of the lever O is pivoted by bein g;notched and inserted in a vhole in the other side of the box A. Thelever O is thrown back to sound the alarm, when re! leased from theratchet N, by one or more springs, R, interposed between it and theplate D. Upon the rear or inner end of the plate I is cast a ange, S,upon the forward side of which is formed a projection, T. By thisconstruction, when the drawer or till is drawn upon without all thebolts E being down, the lng M strikes the lug n of the ratchet N, and,releasing the lever from said ratchet, sounds the alarm. The levers Fare operated by rods U, working` in guides V, attached to the bottom ofthe till or drawer A, and having` fingerpieces XV formed upon orattached to their forward ends.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combina-tion, in a tillalarni clock, of thestraight bolt E, extended bar, trip J 011 top of drawer, and one-ar1nedlever F, substantially as and for the purpose described.
